34 New Species of South American Plants 



Bracts small, produced into attenuate, or filiform tips. Flow- 

 ers I to 3 together, the pedicels i to 2 mm. long, sharply angled, 

 dilated gradually into the turbinate calyx-tube, which is about 

 as long as the triangular-ovate acute lobes, the calyx about 2 

 mm. long. Petals about twice the length of the calyx-lobes, 

 ovate, blunt, lightly keeled. Ligule of the petal extending 

 nearly across the latter, the inner portion about 4-toothed,the 

 outer longer, the petal articulated at the point of insertion. 

 Stamen-tube campanulate, nearly as long as the calyx, the 

 basal glands very small. Ovary ovoid, longer than the tube 

 of the stamens, the styles distinct, tortuous, longer than the 

 stamens, the stigmas small. 



"In thickets by a stream at Masinga Vieja, 8oo feet, April 

 25. A shrub or small tree, 5-15 feet. Rather rare." (Her- 

 bert H. Smith, Colombia, No. 788.) 



Picratnnia villosa. 



Branchlets, inflorescence, petioles, etc., gray-tomentellate, 

 the branchlets finely nerved. Leaves (only the upper seen) 2 

 or 3 dm. long, on short, stout petioles, the leaflets about 5 on a 

 side, not opposite, the petiolules scarcely longer than broad, 

 the blades 4 to 7 cm. long, 2 to 4 cm. broad, the upper succes- 

 sively larger, oblong-ovate, the blunt base mostly slightly in- 

 equilateral, the summit abruptly contracted into a slender rigid 

 acumination, entire, thick, deep-green on both surfaces, some- 

 what shining, the venation coarsely reticulate, slender, lightly 

 prominent on both surfaces, the principal veins tomentellate 

 on both surfaces. Panicle terminal, stoutly peduncled, loosely 

 branched, the branches mostly simple, elongated, stout, spread- 

 ing or recurved, coarsely angled, loosely flowered, the subsessile 

 flowers one to several on short nodes. Sepals 1.5 mm. long, 

 erect or slightly spreading, rigid, ovate, acutish, yellow-tomen- 

 tose. Petals smaller than sepals, oblanceolate, obtuse. Sta- 

 mens rudimentary. Ovary to base of style-branches shorter 

 than sepals, deep purple, oval, a little broader than long, the 

 stout subulate style-branches strongly recurved. Staminate 

 flowers not seen. 



"A tree, probably 30 or 40 feet high, in the forest." (Herbert 

 H. Smith, Colombia, No. 1740.) Triana's No. 5705 in Herb. 

 Kew, under the name "P. villosa", without author and ap- 

 parently not published, apparently the same, has fruits which 

 are 1.5 cm. long, oval-elliptical and black. 

 Protium mucronatum. 



Glabrous, excepting the sparsely puberulent inflorescence. 

 Branchlets stout, striate. Petioles of the foliage leaves i dm. 

 or more long, stout, sub-terete, the rachis somewhat longer, the
